Tests of over 5,000 private wells in Pa. show high levels of arsenic in groundwater

LISLE, Ill. — A report released last week by the US Geological Survey (USGS) showing that one in five private wells in Pennsylvania face elevated arsenic levels offers powerful incentive to test and ensure treatment, according to the Water Quality Association.

“There is hardly any issue more important than clean and healthy water, and this study sends a signal to well owners that they must empower themselves with testing and treatment,” said Dave Haataja, executive director of WQA.

According to the USGS, “Eight percent of more than 5,000 wells tested across Pennsylvania contain groundwater with levels of arsenic at or above federal standards set for public drinking water, while an additional 12 percent — though not exceeding standards — show elevated levels.”

The results highlight the importance of private well owners “testing and potentially treating their water,” the USGS stated.

While public water supplies are treated to ensure that water reaching the tap of households meets federal drinking water standards, private wells are unregulated in Pennsylvania, and owners are responsible for testing and treating their own water, the agency noted.
